We often overlook or ignore the more common critters in the natural world. The eastern gray squirrel and chipmunk come to mind as examples of common critters that many people don’t think about.
The American Crow (Corvus brachyrhynchos) is an exceedingly common bird that I feel is often overlooked. They are found throughout the United States, most of Canada and parts of Alaska, but nowhere else. This is why its common name includes the word “American,” because it is only found in North America.
